Question

​To find rows containing a NULL value in a specified column,you must use the search condition of = NULL.

Quizplus · Accepted Answer

The search condition to find NULL values in a specified column is not = NULL, but rather IS NULL. The = operator does not work with NULL values because NULL is not a value, but a placeholder indicating the absence of a value. Therefore, the correct syntax is column_name IS NULL.
